Description
Non-DoD IM servers can be located anywhere in the world and may be under an adversary's control. If a DoD CMD IM client connects to a non-DoD IM server, malware could be installed on the CMD from the server, or sensitive DoD data on the CMD could be transferred to the server. In addition, if malware is installed on the CMD, this could lead to hacker attacks on the DoD enclave the CMD connects to.

Check Text ( C-44220r1_chk )
Determine if a policy is in place to ensure only DoD managed IM servers are used for the IM service on site-managed CMDs. If a policy is not in place to ensure the IM server the CMD IM applications connect to is not managed by a DoD site, this is a finding.

Fix Text (F-40510r1_fix)
Develop policy to require Instant Messaging (IM) client applications connect only to a security-compliant, DoD-controlled IM server.
